Stainless steel knife blades are considered a compromise by some knife making or bladesmith enthusiasts. Knife making is a hobby that can be enjoyed by young and old. Building a homemade knife is a creative and fun project. A homemade knife can be easily made from an old hand saw, or an old circular saw blade. The tempered steel will create a fine old fashioned knife. This circular saw blade is typically a tool steel with a high carbon content. Custom knives made from high carbon steel are typically easier to maintain a very sharp edge.
Imagine creating with your own hands, a kitchen knife that is so sharp that you could cut the tomato slices "too" thin. All you need is your own labor, sweat, tears, and perhaps a little blood.
Making a fine homemade knife is a work of patience. It is both an art and a science. A good knife is a lot of hard work, dedication to precision craftsmanship, and requires a person to understand the science of metallurgy, and the art of blacksmithing and design.
So, why not stainless steel alloys? Stainless steel may be a good option! There are many stainless alloys with varying properties that will enhance a custom knife. The biggest reason that many custom knife makers are beginning to embrace a stainless alloy, is the age old problem of rust.
Stainless steel is designated as such if it has greater than 13% chromium. Having said that, the ASM Metals Handbook says that it only must be greater than 10%. This difference is probably a reference to "free" or available chromium.
Carbon and stainless steels are both acceptable if properly alloyed. The high carbon steels are typically the steels that are forged. They can be differentially tempered. This property gives the knife maker more options. He can better control the hardness of the cutting edge, and still have a tough knife with a springy back.
But... having said this, consider some of the more popular stainless alloys. The 440 series, particularly 440C, and the Japanese ATS-34 stainless alloy. Also, stainless alloys that have a high vanadium content are more wear resistant and hold an edge better, but are typically harder to work.
Knives, for an accomplished knife maker take anywhere from a few hours for a small utility knife to several months for other, fancier knives. They are an investment and can last a lifetime. Custom knives are often set apart by the exotic materials used.
Knives have always been around in one form or another. When you grip the handle of a great knife, the goal is to have that knife perform as an extension of your arm.
There has probably been at least as many knives made by individual knife makers, working alone, down through history, as have been made by all the factories now making knives.
Regular sharpening and cleaning of a knife will keep it looking great, working well and increase its life. Whether stainless, or high carbon, or something in between, making a custom knife can be an extremely satisfying endeavor.
